Convert XML to YAML online, free. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. YAML is an indentation-based superset of JSON favoured for human-edited config. XML to YAML conversion parses your XML against the W3C XML 1.0 grammar (https://www.w3.org/TR/xml/), builds an in-memory model of its keys, nested objects and arrays, then re-serializes it as valid YAML following the YAML 1.2.2 conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include Kubernetes & Docker Compose manifests, CI/CD pipelines and Ansible playbooks.
It maps the full structure of your XML onto well-formed YAML, following the YAML 1.2.2 conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste XML and convert YAML immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested XML objects, tables and arrays are mapped faithfully onto YAML.
Your XML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
A XML document and its YAML equivalent:
XML input:
<user>
<name>Alice</name>
<age>30</age>
<email>[email protected]</email>
</user>Output:
name: Alice
age: 30
email: [email protected]Paste your XML into the editor and press "Convert to YAML". The tool parses it against the W3C XML 1.0 grammar, then re-serializes it as YAML following YAML 1.2.2 conventions — instantly and entirely in your browser. You can validate or format the XML first to be sure it is clean.
XML has no native numbers, booleans or arrays. Repeated child elements become lists in YAML, attributes and element text become fields, and values stay strings unless YAML coerces them — so review numeric or boolean fields after converting.
Numbers, booleans and null are preserved as native YAML types wherever YAML supports them, so standard documents convert losslessly and can be read back into the same structure.
XML (eXtensible Markup Language) (XML) — XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. YAML (YAML Ain't Markup Language) (YAML) — YAML is an indentation-based superset of JSON favoured for human-edited config. This converter maps the structure of your XML onto YAML so you can use it for Kubernetes & Docker Compose manifests.
Yes. Invalid XML is flagged with a clear error before anything is converted. Common XML problems to check are matched start and end tags, a single root element, and quoted attribute values. Starting from clean input keeps the generated YAML accurate.
Yes. The entire XML-to-YAML conversion runs locally in your browser in JavaScript — your XML is never uploaded, logged or stored. That matters when the data is something like SOAP web services, which should not leave your machine.
The generated YAML is ready for Kubernetes & Docker Compose manifests, CI/CD pipelines and Ansible playbooks. Copy or download it and drop it straight into your tooling.
XML to YAML conversion transforms Extensible Markup Language (XML) documents into YAML (YAML Ain't Markup Language), an indentation-based human-friendly data format. XML is verbose with closing tags; YAML uses whitespace to denote structure, making it cleaner and easier to read. This free tool converts XML to valid YAML instantly in your browser — no upload, no signup, and your data never leaves your device.
Converting XML to YAML takes three steps and happens instantly in your browser:
XML uses nested tags and attributes; YAML uses indentation (whitespace) to denote nesting. When converting, XML elements become YAML keys, and nesting is preserved via indentation rather than closing tags. XML attributes are commonly mapped to sibling keys or prefixed entries. YAML is far more compact and human-readable, making it the standard for Kubernetes manifests, Ansible playbooks, and CI/CD pipelines.
Paste your XML above and convert it to clean, readable YAML in one click. Whether you are deploying to Kubernetes, writing Ansible playbooks, modernizing CI/CD pipelines, or migrating infrastructure configs, this tool generates accurate YAML instantly and privately.
